Согласно ckeditor, если вы используете класс "ckeditor", он автоматически сгенерирует редактор.Как показано ниже.
<textarea class="ckeditor" required="" name="question_option_1" ></textarea>
<textarea class="ckeditor" required="" name="question_option_2" ></textarea>
<textarea class="ckeditor" required="" name="question_option_3" ></textarea>

Похоже, вы хотите клонировать ckeditor.
